Visiting my Aunt

My late father's sister Helen 50 single no children is my only living relative on my father's side of the family. Helen lives alone in a small town 30 or so miles from the the city I live in. I'm Norman 32 after my father and have done quite well career wise and not so good relationship wise. My mother lives with my older sister on the coast, I decided I needed a break. But didn't want to go to the coast, so I decided to go and visit Helen, I drove out to see her and had a nice visit with her. She told me she had to go to the city for some tests the next month and would be there for about 3 or 4 days. I thought I should offer her a place to stay and she accepted and I returned home. I live in a 2 bedroom apartment and I'm not the tidiest person going so I got a my apartment cleaned for Helen's visit, the week before she was coming. On her arrival we caught on the usual things and as I'm no great cook, I took her out for dinner. The next day she had her first tests and again I took her out for a meal. Same again the next day, except we then saw a movie together and had a few drinks before go back to my place. Helen liked a drink and had a few too many, but that was no problem. On our return to the apartment we were both a little merry you could say. Helen took off her coat and caught the buttons on her top and the top opened. Showing me me her sexy bra and she has great tits. I couldn't help myself and asked was she horny, not expecting a positive reply. But she said I'm always horny and I added okay let's fuck, she just nodded and we went to my bed and fucked. She really drained my balls and we had another fuck in the morning. Helen had intended to return home that afternoon, but decided to stay longer and get fucked. She ended up staying another week and she slept with me every night. After a week of being alone again I decided to visit Helen again and on my arrival she asked how I was and I replied very horny and so we went to her bed and fucked. I returned home the next afternoon and have since visited Helen every chance I get for sex. Last week I had to stay home as I had to finish up a job, but Helen came to visit me and I only just got the job finished on time. Helen is a very horny woman and if she wasn't so reserved she would be fucking everyone she met. But thankfully she is and I get to fuck her instead.
